If network speed means a lot to you, here is a video comparison of iPhone 4S with 3 different network speeds in the US. You can choose between AT&T, Sprint and Verizon. The test shows the loading of websites, video and also runs SpeedTest application on all three networks. Guess, who is the winner.

Just remember that you might get different results, because it depends on your location.

Today Apple has begun selling its new iPhone 4S in seven countries: US, Canada, UK, France, Germany, Japan and Australia. The device is available in two colors (black, white) and three storage sizes (16 GB, 32 GB, 64 GB). As usual, lines have begun forming near Apple Stores worldwide and Apple Store employees were pulling overnight shifts to put up new displays and promo materials for the iPhone 4S launch.

The Japanese launch was hampered by registration slowdowns from Softbank, according to the Wall Street Journal:

The launch of the iPhone 4S in Japan was interrupted when Softbank – the main service provider for Apple products in the country—suffered a server glitch that temporarily suspended sales nationwide. A company spokesman said the servers were unable to process registration information.

Apple has already received more than one million pre-orders for the iPhone 4S. Analysts are predicting that weekend sales will exceed the iPhone 4 which were sold 1.7 million units its opening weekend. Estimates range from 2 million to 4 million.

As usual, iFixit conducted their standard teardown of Apple's latest gear, this time it was Apple’s next generation iPhone 4S. The device has largely the same design as the iPhone 4, but inside it is different. The new iPhone 4S has a slightly larger battery that improves battery capacity and offers extra hours of talk time, comparing with the iPhone 4.

Other new thing implemented in the iPhone 4S is the A5 chip that improves performance up to seven times, comparing with the iPhone 4. The A5 CPU has a marking of E4E4 with 512MB of RAM. The teardown also revealed a new Qualcomm MDM6610 baseband chipset that is the slightly modified model of the “worldwide” MDM6600 Qualcomm baseband used in the CDMA iPhone 4 that, as you remember, has both CDMA and GSM modes, but works in only CDMA networks. The iPhone 4S is the true worldwide smartphone, which will allow both GSM and CDMA customers to roam on GSM networks worldwide

Above you can see a hands on video of Siri and some other features on new iPhone 4S. Apart from some practical examples, the reviewer asks such questions and statements as "I Love You" and "How Old Are You".

The iPhone 4S is still believed to have 512MB of RAM, just like the iPhone 4. The Infinity Blade developer, who suggested that, found out this fact when he tried to demo his game on the new iPhone 4S during last week's keynote.

"I'm still shocked that, with the iPhone 4S, I'm literally running around with a 1080p video camera in my pocket, with an eight megapixel camera, 64GB of hard drive space and an A5 chip with 512MB of memory. This is a really powerful computer, right?

AppVV also confirms that the iPhone 4S has 512MB of RAM. This fact is repeated on their Weibo page as well in response to a question:

German website Macerkopf.de. has reported that some German customers have apparently received their pre-ordered iPhone 4S ahead of its official launch, October 14th. The iPhone 4S pre-ordered through Deutsche Telekom was delivered this morning. The lucky customer promptly shared photos of the packaging, device and Siri.

In the first 12 hours of the iPhone 4S availability AT&T reported that had received 200,000 pre-orders, Sprit, which also offering the iPhone 4S, said that they were very pleased with initial demand. This is the new record for Apple. The iPhone 4 saw 600,000 pre-orders in 24 hours last year.

Apple today announced pre-orders of its iPhone® 4S have topped one million in a single day, surpassing the previous single day pre-order record of 600,000 held by iPhone 4. iPhone 4S is the most amazing iPhone yet, packed with incredible new features including Apple’s dual-core A5 chip for blazing fast performance and stunning graphics; an all new camera with advanced optics; full 1080p HD resolution video recording; and Siri™, an intelligent assistant that helps you get things done just by asking.

“We are blown away with the incredible customer response to iPhone 4S,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “The first day pre-orders for iPhone 4S have been the most for any new product that Apple has ever launched and we are thrilled that customers love iPhone 4S as much as we do.

AT&T has officially announced that they have processed 200,000 pre-orders for the iPhone 4S. It looks like new Apple smartphone is the most successfully launched iPhone yet. These 200,000 orders only come during the first 12 hours of sales

AT&T has seen extraordinary demand for iPhone 4S with more than 200,000 preorders in the first 12 hours alone, the most successful iPhone launch we’ve ever had. It’s obvious customers like AT&T’s 4G network, which is the only one that lets their iPhone download twice as fast and talk and surf simultaneously.

These numbers don't include Apple's own online pre-orders or the orders through Verizon Wireless and Sprint.

Samsung and Google announced that they would cancel a special event which is scheduled for Tuesday and at which the companies were going to introduce their new handset Nexus Prime. The particular feature of this smartphone is the brand new software, Google's latest "Ice Cream Sandwich" version of Android. Rumors immediately turned to the possibility that the companies postponed the launch in respect for Steve Jobs who passed away on October 5th.

Samsung and Google decide to postpone the new product announcement at CTIA Fall. We agree that it is just not the right time to announce a new product. New date and venue will be shortly announced.

AllThingsD has confirmed that speculations. The site claims that Samsung and Google did indeed cancel the event due to Jobs' death.

The decision to postpone things was made late last night at the top levels of both companies, sources said, with Jobs’ death being the reason. There are no delays with the product itself, sources insisted.

But Apple is not going to cancel its plans for the iPhone 4S, having started accepting pre-orders for the device.

As Apple promised, pre-orders of expected iPhone 4S is become available. Now it is possible to pre-order new iPhone through Apple’s website in Australia, Germany, France, Canada, the United States, Japan and the United Kingdom.
